Extrusion molded product for e.g. passenger car, has core material made of hard synthetic resin, and soft synthetic resin coating bodies in which one body has embedded part with support elements and pushed towards inner peripheral surface

摘要

The product has a core material (2) made of a hard synthetic resin e.g. polypropylene, and with a U-shaped cross section. Outer and inner peripheral coating bodies (3, 4) are made of soft synthetic resin e.g. olefin resin, and cover outer and inner peripheries of the material, respectively. One of the bodies has an embedded part (6) to form a part of the coating body and extends towards the bottom from a lower end of the material so as to be pushed towards an inner peripheral surface of the material. The embedded part has support elements (7) formed in an outer periphery of the part (6).
